The article is devoted to the study of methods and means that help to improve traction and traction characteristics of power vehicles, in particular tractors, when performing combined operations of soil treatment. The article analyzes the impact of weight distribution, tire pressure, and the use of special devices on the quality of tillage operations.
It was established that the efficiency of combined tillage operations depends on the level of traction and traction characteristics of the power tool. To increase traction characteristics of the tractor, it is proposed to use mathematical methods of increasing tire pressure and optimal weight distribution on the axle. The article also describes special devices for increasing traction resistance, which help to provide better traction and increase traction characteristics. This article examines the influence of soil parameters on traction and traction characteristics of an energy vehicle during combined soil treatment operations. It was found that soil indicators, such as moisture, density and fractional composition, have a significant impact on the quality of soil processing operations and traction characteristics of the tractor.
To solve this problem, methods of increasing traction and traction characteristics are proposed, such as a mathematical method of increasing tire pressure and a method of optimal weight distribution on the suspension. The use of special devices to increase traction resistance, which help to ensure better traction and improve traction characteristics, is also considered.
The research conducted by the authors can be useful for tillage and tractor maintenance specialists who are engaged in optimizing the operation of energy equipment at agricultural enterprises.
